Among Optoma's innovations at the recent ISE tradeshow in Barcelona was the introduction of four new projectors, including the company's first 4K models with an affixed lens.
The new ZK810T and ZK810TST, introduced only for the European market for now, follow a pathway Optoma pioneered in 2020 with its ZU720 series, which pushed brightness to 7,500 lumens at a then unheard-of $4,999 thanks to the novel approach of eschewing interchangable lenses in that brightness class with a cost-effective, permanently attached zoom lens. The company's ZU920T and ZU920TST followed.
The ZK810T and its ZK810TST short-throw sibling now take that concept to the company's first 4K UHD models (3840x2160), each offering 8,600 lumens (of unspecified type) and 7,200 ANSI lumens. The ZK810T utilizes a motorized 1.6X zoom lens with a 1.26:1-2.0:1 throw ratio, equipped for 16:9 images up to 300 inches diagonal. The ZK810TST short-throw has a 1.15X motorized zoom with a 0.65:1 to 0.75:1 throw ratio, for images of 30-300 inches diagonal (0.76-25.4 meters), achieved with throw distances of 2.3-54.5 feet (0.7-16.6 meters). Along with zoom capabilities the projectors achieve installation flexibility with motorized vertical and horizontal lens shift and four-corner geometric correction.
Both projectors feature a sealed, dust-resistant, IP5X certified DuraCore laser engine with up to 30,000 hours of maintenance-free life (Eco mode). The projector's support 360-degree projection, portrait mode, and 24/7 round-the-clock operation. Both are also compatible with HDR10 and HLG high dynamic range content to go along with their 4K resolution.
Connections on both models are robust and include two HDMI inputs and one output, HDBaseT for digital input/control, USB-B and USB-A (power), 3D Sync in/out, a 3.5mm audio output as an alternate to the pair of 10-watt on-board speakers, and additional control options including a dedicated LAN port, RS-232, 12V trigger, and 3.5mm remote in (compatible with a 3.5mm output on the handheld remote). Additionally, Optoma says it has made improvements to the remote IR sensor for improved range over earlier models.
The new series is also compatible with the Optoma Management Suite, Optoma's solution for local or cloud-based fleet management that allows admins to monitor, diagnose, and control multiple audio visual displays in real-time.
Other introductions at ISE included two WUXGA-resolution laser models targeted at conference rooms and classrooms, the ZU607TST short throw and ZU707T standard throw projectors. The ZU607TST is spec'd at 6,000 lumens (unspecified) and 4,800 lumens (ANSI), and offers a fixed-zoom 0.58:1 lens for throw distances of 1.25-12.3 feet (0.38-3.75 meters) for 16:10 images of 30 to 200 inches (0.76-7.62 meters). The ZU707T is rated for 7,000 lumens (unspecified) and 5,900 ANSI lumens, on a chassis equipped with 1.6X manual zoom lens with a 1.2:1-1.92:1 throw ratio. Both models offer vertical and horizontal lens shift and sealed, long-life DuraCore laser engines rated for 360-degree orientation and 24/7 operation. They also offer compatibility with 4K, HDR10/HLG input signals, among other features.
